If you have a fungus, what works better: cream or powder
Powder
Inhibits bacterial cell wall synthesis
Bacitracin
Rapid onset; large surface area for systemic absorption
Chance of tissue irritation and patient compliance

Injection
Chance of infection if sterility not maintained
Injection
Local effects on surface of skin but only effective in treating outer layers of skin
Topical
Introduces drug into body without breaking the skin
Drug must be able to pass through dermal
layers intact
Transdermal
Easy, safe, and convenient

Rapid onset
Drugs must be easily absorbed from oral mucosa
Sublingual
Alternative to oral route
